HTTP POST request and encoded string

Posted By:      Posted Date: October 15, 2010    Points: 0   Category :.NET Framework


I have to do a simple HTTP POST request by key/value pairs and receive a XML file with a session key. I made it work, but there's something strange about it - when session key includes character '&', then it return encoded like '&'. After that my application needs to send that session key to server every time I make a query. When session key includes '&', then query won't work, because server side is expecting correct (not encoded) session key. Does somebody knows how to fix this problem? My HTTP POST Content-type is "application/x-www-form-urlencoded".

HTTP Post and WebService


I am working on a application which will accept the data in the post request. My application also wants to expose a web service and want to call another web service. Considering all these 3 action that I want to do, can I create a single application which will have a web form which will accept the POST request and expose a web service at the same time.

Although it may be possible to achieve this, Is this a correct way of doing it?

HTTP Pipelines: Securely Implement Request Processing, Filtering, and Content Redirection with HTTP


ASP.NET is a flexible and extensible framework for server-side HTTP programming. While most people think of ASP.NET in terms of pages served, there is a lower-level infrastructure sitting beneath this page model. The underlying plumbing is based on a pipeline of app, module, and handler objects. Understanding how this pipeline works is key if you want to get the most out of ASP.NET as an HTTP server platform, while making your process more efficient, and keeping your server secure. This article introduces the architecture of the pipeline and shows how you can use it to add sophisticated functionality to an ASP.NET-based app.

Anonymous Web Site receives "The request failed with HTTP status 401: Unauthorized"


I set up a test website on my local box and was able to access sharepoint search using the querySearch web service from SP.  After I got it all working properly I transferred the code to the target website that is set up with anonymous access for all people on the fab floor.  However from this website I keep getting the 401 error.  It can't be SP because the same code worked from my local website "localhost".  Any suggestions?  we don't want to have to have the fab people log in so we can't not have the box anonymous.  I would appreciate any suggestions very much!!!

HTTP 400 Bad Request Error when uploading to document library


I am running MOSS 3007 Standard on Windows 2003. When trying to upload files larger than about 29Mb, I am getting an HTTP 400 Bad request error. The error states "HTTP Error 400 - Request is badly formed." I am able to successfully upload a 28Mb file. Sharepoint is configured to accept files up to 75Mb.

I have done a fair amount of research on this, but none of the solutions seem to apply to our environment. The two most likely candidates do not apply, for example we are NOT running URLScan (there are a variety of solutions suggesting this could be an issue with uploads of 30Mb or more), and we are on 2003 with IIS6, so again the issue relating to 2008 and IIS7 do not apply.

The "Request is badly formed" part of the request is particularly confusing as most issues I have come across where this error is the symptom point to errors in custom code that is trying to talk to SharePoint. We have done none of our own custom coding and this error is occurring when attempting a simple upload to a document library.

Trying to drag and drop the file across when the document library is open in windows explorer also fails.

I did come across someone saying they had a similar problem which was caused by a damaged content database, however in this case, it is occuring regardless of which content database I use, so either they are all corrupt

How to bind a WCF Http client to a specific outbound IPAddress before making the request

WCF webservice: HTTP/1.1 400 Bad Request while sending large input
